* | * A grindometer is used to assess the particle size distribution in a battery slurry, which is critical for ensuring uniformity and optimal performance. By measuring how finely the active materials and conductive agents are dispersed, the grindometer helps in determining the slurry’s consistency, which directly impacts the battery's electrochemical properties and cycle life. | ||
